Version 1.5

Version 1.5.0-beta03

July 16, 2025

androidx.camera.viewfinder:viewfinder-compose:1.5.0-beta03, androidx.camera.viewfinder:viewfinder-core:1.5.0-beta03, and androidx.camera.viewfinder:viewfinder-view:1.5.0-beta03 are released. Version 1.5.0-beta03 contains these commits.

Bug Fixes

• The default ImplementationMode for Viewfinder (both Compose and View-based) now intelligently selects between EXTERNAL (for performance) and EMBEDDED (for compatibility on older APIs/quirky devices). This behavior can still be overridden by explicit settings in ViewfinderSurfaceRequest or XML attributes (on the View-based API). (Iecd3a)
• Improved Surface session management by allowing the ViewfinderSurfaceSession to be kept alive across surface create/destroy lifecycles when using TextureView or SurfaceView on API 29+. (I112d9)
• The Viewfinder now ensures Surfaces are released at the proper time, only when no longer in use by the session, rather than always releasing when the Composable is disposed. For EXTERNAL (SurfaceView) this behavior is currently only available on API 29+. For EMBEDDED (TextureView), this behavior is present on all API levels. (I9a03f)
• The Viewfinder now properly handles surface replacement in scenarios such as when an EXTERNAL viewfinder on API level 28 or lower moves off screen or if a Viewfinder (with any ImplementationMode) is part of moveableContentOf(). (I79432)
• Composable Viewfinder now works correctly with Compose's Pager. This change ensures that the Composable can be successfully reset by implementing the onReset callback of AndroidView, supporting both EMBEDDED and EXTERNAL implementations. (I0d9be)
• Fixes an issue on Android 10/11 where the EXTERNAL Viewfinder could appear stretched or incorrect due to transformation operations (like scale or translate) being applied too early. The system now waits for the Surface to be created before applying these transformations in the layout phase, ensuring correct output. (Icc77c)

Version 1.5.0-beta02

June 4, 2025

androidx.camera.viewfinder:viewfinder-compose:1.5.0-beta02, androidx.camera.viewfinder:viewfinder-core:1.5.0-beta02, and androidx.camera.viewfinder:viewfinder-view:1.5.0-beta02 are released. Version 1.5.0-beta02 contains these commits.

Version 1.5.0-beta01

May 7, 2025

androidx.camera.viewfinder:viewfinder-compose:1.5.0-beta01, androidx.camera.viewfinder:viewfinder-core:1.5.0-beta01, and androidx.camera.viewfinder:viewfinder-view:1.5.0-beta01 are released. Version 1.5.0-beta01 contains these commits.

• This is the first official beta release of the view-based and compose-based viewfinders that are flexible enough to be used with Camera2. If you’re looking for a View or composable to use with CameraX, see PreviewView and CameraXViewfinder.

New Features

• ContentScale and Alignment can now be used in the compose-based viewfinder to scale and place the displayed surface within its container, similar to how androidx.compose.foundation.Image behaves. (Ibcea3)

API Changes

• TransformationInfo now has default values for all args. This will allow Viewfinders to be created without any TransformationInfo, which will default to a source rotation of 0, no source mirroring, and no crop rect. (I2b1b2)
• Composable Viewfinder now takes a trailing lambda to receive a Surface session, similar to AndroidExternalSurface. The provided lambda uses ViewfinderInitScope as a receiver, which allows installing a callback to receive new Surface sessions. These surface sessions automatically release resources held by the Viewfinder when they go out of scope. (Ib2b0d)
• ViewfinderSurfaceRequest.Builder.populateFromCharacteristics has now been removed and is now replaced with an equivalent set of static APIs that can be used to generate TransformationInfo which will produce the same transformation as populateFromCharacteristics. These static methods are added to the Camera2TransformationInfo class. (Idc6af)
• ViewfinderSurfaceRequest no longer includes async APIs for retrieving the surface. It is now an immutable data type. APIs for retrieving the Surface are now moved to the viewfinder. (I30127)
• CameraViewfinder has been renamed to ViewfinderView so that the naming aligns with the naming of the Viewfinder composable and to indicate that it can be used with more than just camera sources. (Id9e6b)
• Classes from viewfinder-view have been moved to the androidx.camera.viewfinder.view subpackage from the androidx.camera.viewfinder package. (I6cb44)
• New APIs are added to view-based Viewfinder that allow setting the source rotation, mirroring, and crop rectangle. This TransformationInfo class is the same class used by the compose-based Viewfinder. (I907c3)
• The view-based Viewfinder now uses new ViewfinderSurfaceRequest APIs which no longer internally handle the Surface response. Instead of returning ListenableFuture<Surface>, the requestSurfaceSession() APIs now return ListenableFuture<ViewfinderSurfaceSession> which returns an AutoCloseable class that when closed behaves the same way as calling the old API of ViewfinderSurfaceRequest.markSurfaceSafeToRelease(). This provides a clearer separation of responsibilities between the surface request and surface response. (I19041)

Version 1.4

Version 1.4.0-alpha13

February 26, 2025

androidx.camera.viewfinder:viewfinder-compose:1.4.0-alpha13, androidx.camera.viewfinder:viewfinder-core:1.4.0-alpha13, and androidx.camera.viewfinder:viewfinder-view:1.4.0-alpha13 are released. Version 1.4.0-alpha13 contains these commits.

Version 1.4.0-alpha12

January 15, 2025

androidx.camera.viewfinder:viewfinder-compose:1.4.0-alpha12, androidx.camera.viewfinder:viewfinder-core:1.4.0-alpha12, and androidx.camera.viewfinder:viewfinder-view:1.4.0-alpha12 are released. Version 1.4.0-alpha12 contains these commits.

New Features

• Upgraded compileSdk as 35 for using Android 15 related API. Apps using CameraX libraries will also need to upgrade their compileSdk config setting. (Ic80cd)
• This library now uses JSpecify nullness annotations, which are type-use. Kotlin developers should use the following compiler argument to enforce correct usage: -Xjspecify-annotations=strict (this is the default starting with version 2.1.0 of the Kotlin compiler). (I7bcd7, b/326456246)

Version 1.4.0-alpha11

December 11, 2024

androidx.camera.viewfinder:viewfinder-compose:1.4.0-alpha11, androidx.camera.viewfinder:viewfinder-core:1.4.0-alpha11, and androidx.camera.viewfinder:viewfinder-view:1.4.0-alpha11 are released. Version 1.4.0-alpha11 contains these commits.

API Changes

• viewfinder-core classes have been moved into packages that are consistent with the library they belong to. (I431c6)
• CameraViewfinder.ScaleType has been moved to viewfinder-core so it can be reused with compose (I87ef1)
• Deprecated CameraViewfinder classes are removed. Please use the new APIs which provide equivalent functionality. (I6e59a)

Version 1.4.0-alpha10

October 30, 2024

androidx.camera.viewfinder:viewfinder-compose:1.4.0-alpha10, androidx.camera.viewfinder:viewfinder-core:1.4.0-alpha10, and androidx.camera.viewfinder:viewfinder-view:1.4.0-alpha10 are released. Version 1.4.0-alpha10 contains these commits.

Version 1.4.0-alpha09

Version 1.4.0-alpha08

September 4, 2024

androidx.camera.viewfinder:viewfinder-compose:1.4.0-alpha08, androidx.camera.viewfinder:viewfinder-core:1.4.0-alpha08, and androidx.camera.viewfinder:viewfinder-view:1.4.0-alpha08 are released. Version 1.4.0-alpha08 contains these commits.

New Features

With the update to 1.4.0-alpha08, the CameraX Viewfinder artifact has been moved to its own library group. This change is necessary to improve the modularity and maintainability of the CameraX library.

If you were previously depending on androidx.camera:camera-viewfinder, androidx.camera:camera-viewfinder-compose or androidx.camera:camera-viewfinder-core, you will need to transition your dependencies to the following:

• androidx.camera:camera-viewfinder -> androidx.camera.viewfinder:viewfinder-view
• androidx.camera:camera-viewfinder-compose -> androidx.camera.viewfinder:viewfinder-compose
• androidx.camera:camera-viewfinder-core -> androidx.camera.viewfinder:viewfinder-core

No code changes should be needed to make this transition. The old Viewfinder maven coordinates will no longer receive updates.

Additionally, if you are using Compose with CameraX, a new Compose-first library is now available in alpha: androidx.camera:camera-compose. This provides the CameraXViewfinder composable, which is a compose-idiomatic Viewfinder that adapts CameraX’s SurfaceRequest to Compose, similar to how PreviewView works for views.
